摘要
以叶尔羌河中下游平原区主要水文观测断面和典型河段来水来沙条件及河床边界组成条件的分析为依据,以影响冲积平原河流河床演变的三大主要影响因素的辨识分析为基础,进行了叶尔羌河平原区游荡河型形成原因的分析,得到了叶尔羌河平原区游荡河型的首要成因是河床边界组成条件,辅助条件是来水来沙条件的初步结论,并据此建议流域治理应秉持中下游河道防洪护岸工程建设与上游大型枢纽控导工程并举的方略。
Based on the analysis of incoming water and sediment of main hydrological observation and typical reach and riverbed boundary condition in middle-lower reaches of the Yarkant river,and the analysis of three major factors which have influence on alluvial river riverbed evolution,the paper has analyzed the cause of formation of wandering type river in plain areas of the Yarkant river.The preliminary conclusion shows that the main cause is riverbed boundary condition and the subsidiary condition is incoming water and sediment.According to the above results,it is suggested that both flood prevention and bank protection in middle-lower reaches and large-scale hub control engineering in the upper reaches should be constructed when it comes to basin management.
